Challenging Pianus Boss

EDIT: Or maybe like this, to be able to actually get the drops?

 Spoiler

Just make the map smaller so pianus is floating just BARELY above range of hitting him while standing on the spikes.

How to get to the boss:
Kill Right Pianus while Left Pianus exists. A portal appears where right Pianus is after killing him.
HARD AS pineapple. All I gotta say.

HP: 166,000,000
Moar HP pl0x.

Elements: Weak to Fire
Make it weak to something else. It should be like, Holy Weak, considering its a freakin ghost.
Skills: "Reverse Directions" curse (forgot the name), Super KB with Beam attack
How the hell does Super KB work in water? Do you float across the map really fast or something? And wouldn't Rev.Dir. mean you have to hold down just to go up in the water? That's just cruel.

Comments in green. Love the idea Fiel. Need a few tweaks, but its honestly a very fresh idea. And TY for getting rid of the stupid Blood Booms. They're the only reason I never hunt Pianus.
